Is port 175 dangerous?

We have no specific security note for port 175. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 175, and is it reachable?

Linux

sudo ss -ltnup 'sport = :175'      # process listening on 175
sudo lsof -nP -i :175

macOS

sudo lsof -nP -i :175

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 175 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 175
netstat -ano | findstr :175

From another machine

nmap -p 175 -sV <host>
sudo nmap -sU -p 175 <host>
nc -zv <host> 175

Block it in the firewall

sudo ufw deny 175/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 175" -Direction Inbound -LocalPort 175 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 175 used for?

Port 175 is assigned by IANA to vmnet (VMNET).

Is port 175 TCP or UDP?

Port 175 is registered for TCP and UDP.

Is it safe to open port 175?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 175 is open?

On Linux run "ss -ltnup 'sport = :175'", on macOS "lsof -nP -i :175", and on Windows "netstat -ano | findstr :175" to see the local process. From another machine, "nmap -p 175 <host>" shows whether it is reachable.
